In comparing the virtual library to the traditional one of paper and ink, we need to remember several things: that reading often requires slowness, depth and context; that our electronic technology is still fragile and that, since it keeps changing, it prevents us many times from retrieving what was once stored in now superseded containers; that leafing through a book or roaming through shelves is an intimate part of the craft of reading and cannot be entirely replaced by scrolling down a screen, any more than real travel can be replaced by travelogues and 3-D gadgets
